car non- COLLAPSIBLE moans Application filed April 24,

The object of the invention is to provide a cap for collapsible tubesequipped'with a simple and yet effective anchoring means securing it tothe tube and preventing its loss when displaced from the dischargemouth.

With this'bbject in View, the invention consists in a construction andcombination of parts of which a preferred embodiment is illustrated inthe accompanying drawings,

wherein: f

Figure 1 is ah side elevational view of a collapsible tube showing the.invention ap-- plied in operative position thereon.

Figure 2 is a central vertical sectional view through the structureshown in Figure 1.,

\ Figure 3 is'a transverse sectional viewon" the plane indicated by theline 3-3 of Figure 2. Figure 4 is a sectional view on the planeindicated' by the line'4 l 0f Figure 2.

'Figure 5 is a perspective v-iew of the filler. Designed as a means toprevent the loss of the cap 10, when detachedfrom thedischarge nipple 11of the collapsible tube 12, the invention comprises a single strand ofspring steel wire constituting an, anchor 14, the strand at one end beinformed with an eye 15 engaged in a hole 0 a lugf16 secured to the topportion of the tube, as indicated.

The remoteterminal of the anchor is extended through a central hole 17"in thecap. 10 and is terminally formed with a spiral 18lying against theunder face of the cap,"a

ripheral wall of the cap, so that the filler is thus efi'ectivelyretained in place.

This construction provides for swivel connection between the anchor andthe cap and, when the latter is attached, the anchor forms a loop bywhich the connected tube may be hung on a hook or other hanger.

The invention havingbeendescribed, what is claimed as new and useful is:

In combination with a collapsible tube and cap therefor, an anchorhaving a swinging connection with the tube and a swivel connection withthe cap at a central point on the top of the latter, the cap beingconical interiorly and terminating at its apex in an opening, the anchorat the point remote from the point of connection with the tube extendingthrough said opening and being formed a with a-spiral abutting the underface of the cap, and. a ductile filler insertedin the cap 7 below saidspiral, the filler being in the form of a cone snugly fitting the capinteriorly withits. apex extending upwardly into the apex of the cap. V

In testimony whereof he aflizges his signa ture.

a ,MARION D.-- J'U'DKINSIJ filler 19 being inserted in the cap from theinside toact as a stop against which the spiral may engage and thuspreclude the cap, when detached frOm the tube, from slidinglongitudinally of the anchor. The filler also serves asmeans to-presentan air tight joint between the cap and the nipple tube when the cap isattached. u I

of the The filler is made Offl ductile met-a1, preferably lead, moldedin a conical form, as 45 shown in Figure 5. At the base portion, it isof a diameter to pass readily into thecap' and is placed withthe apexoutwardly.
